In Discovery, which one of the following should the customer always configure during implementation? A. Probes B. Credentials C. Subnets D. Change Management

### B. Credentials

## Step1: Understanding the Question### The question is asking about the necessary configuration that a customer should always set up during the implementation phase of Discovery.## Step2: Analyzing the Options### We have four options: Probes, Credentials, Subnets, and Change Management. We need to determine which one is the most critical to configure during the implementation phase.## Step3: Evaluating the Options### Probes are used for monitoring network traffic, Subnets are used for dividing an IP network into smaller parts, and Change Management is a process to manage changes in an organization. While all these are important, none of them are as critical as Credentials. Credentials are used for authentication and access control, which are fundamental to any implementation process.
